Only the Owner or an Admin will have the ability to upgrade a User to an Admin. If the contact you would like to upgrade has not been invited to RightNow Media @ Work, you can select "Admin" when sending them a new invitation from the contacts page.
If you want to upgrade a contact who is already in the system as a User, you can upgrade them from the contacts page. After logging into RightNow Media @ Work, go to the contacts page by clicking the contacts link in the upper right corner.
Next, select the contact(s) that you would like to upgrade to Admin(s).
Finally, click the "Selected" drop down menu and choose "Make Admin."
